Leviticus 14:21-24

21“But if he is poor and cannot afford it, then he shall take one male lamb as a trespass offering to be waved, to make atonement for him, one-tenth of an ephah of fine flour mixed with oil as a grain offering, a log of oil,

22and two turtledoves or two young pigeons, such as he is able to afford: one shall be a sin offering and the other a burnt offering.

23He shall bring them to the priest on the eighth day for his cleansing, to the door of the tabernacle of meeting, before the Lord.

24And the priest shall take the lamb of the trespass offering and the log of oil, and the priest shall wave them as a wave offering before the Lord.
